文摘
The precise functionalization of self-assembled nanostructures with spatial and stereocontrol is a major objective of nanotechnology and holds great promise for many applications. Herein, the nanoscale addressability of DNA origami was exploited to develop a precise copy-machine-like platform that can transfer two-dimensional oligonucleotide patterns onto the surface of gold nanoparticles (AuNPs) through a deliberately designed toehold-initiated DNA displacement reaction. This strategy of DNA-origami-based nanoimprinting lithography (DONIL) demonstrates high precision in controlling the valence and valence angles of AuNPs. These DNA-decorated AuNPs act as precursors in the construction of discrete AuNP clusters with desired chirality.
